I have used this plugin on a number of sites, with a number of unique designs and features in their forms. I have been able to implement each without undue difficulty, and they have performed reliably.

While I think that Contact Form 7 could be improved a lot, it deserves 5 stars for doing an important job well - and free!

Contact form 7 is by far the best plugin for contact us page on website. I really it due to its options and ease in implementation.

One thing I don't like is that I just have a one page for contact form but the plugin code appears in every single page/post of my website ( it can be viewed using source view ). If possible, try that code does not appear on other pages
